My daewoo lanos 1.6 auto is noisy while driving

There are various ideas here, but the only way to be sure is to have an auto electrician connect a pro grade scan tool computer and take it for a run. The scan tool can record what happens when it starts to misfire.

Oxygen Sensor

1999 Daewoo Lanos 1.6L MFI DOHC 4cyl

The Oxygen Sensor is located: Under hood, driver side, lower engine area, above exhaust pipe flange, mounted in exhaust manifold,don't have a picture.Here's a link to what it look's like just remove the electrical connector,get a open end wrench and remove.. http://www.autozone.com/engine-management/oxygen-sensor/bosch-oxygen-sensor/daewoo/lanos/1999/4-cylinders-6-1-6l-mfi-dohc/4971_102074_1784_97999

lift gear lever boot. if manual car or on gearbox if auto

No
Check with an auto parts store
or another web site

new plugs and air filter ,is my first solution but as its a auto then it could be the gearbox slipping which would be caused by the front clutch in the box worn ,also the autochoke could be stuck on causing excesive fuel consumption ,in the uk in the old days we had lots of mechanics stories of women pulling the manual choke out to hang the handbag on ,or american tourists driving in first gear as they didnt know how to change gear .,Or the old man with reumatism driving with his foot on the clutch .Try the air filter first

pull plug and take to auto parts store

put it up in the air and have a good look around ,most likely is a connection ??

Few problems, check for noisy engine and uneven tyre wear,generally not a bad cheap car but they depreciate quicker than apple falling from a tree! So make sure it is a good deal.

Good luck davelee
